Great video. I'm going to show it to my students. They will see more than cutting the thread, you actually go over several lathe components and demonstrate how they work. This is awesome!
Thank you sir for showing how and where to place the protractor to achieve the correct angle. I am using a 9 in South Bend, but the concept is the same. I immediately put you on pause and went out into my shop. Sure enough your idea works great. I checked with the dial markings and they were the same as the protractor. Thanks again. Hey don't worry about the accent, I am from "New England" Massachusetts, and I get crap about my accent. Gotta admit though we don't sound much alike :-) . Thanks again.....Marina California (now) .
i've been imagining this, though it is one of the easiest method, and this man in video is really intelligent as he showed it up ! thank you sooooooooooooooooo much for uploading this video.
Took me a while to work out what a "27.5 degree wooden head" was. Couldn't see anything wooden! But very impressive and helpful - thank you. Don't suppose you'd like to live under the bench in my shed... I could get you out on Saturdays and do something right for a change.
Hello sir,i just bought an very old lathe and i want to make a dummy spindle for making some backplates for some chucks i have, i just find your video realy helpfull! Thank you!
Looking good as always John...and I didnt get the urge to have a snack this time...LOL Great camera work as well, you put a lot of time into it! Colin ;-)
DrPococksMagicPills I've watched this video several times over the last two years and each time the ECU's of the threads being cut appear, it makes my day! Beautiful!! Thanks again, John for creating these videos. Roy Lewis, Buffalo, NY. USA
doubleboost Great work as usual. Do you plan on making that into an adapter for your lathe there? Bore the inside and thread it for your spindle nose? Very nice work, you sure can't complain about the finished product after you put that indicator on there.
you need a sensor at the end of the thread and an electromagnet for clutch disengagement. To fit the lock solenoid actuator from the car alarm. The sensor may be a simple switch
Nice one John! I had to LOL @ the "wooden head" bit. But that brings up an odd question... If Pinocchio told the same lie repeatedly, would his nose grow only once, or grow each time?? If each, the same length every time? Or exponential growth per occurrence? Damn, I think too much! :))
hi ya double ,, great vids ,,, my boxford bud is also run on an inverter ,, do you have problems with the machine "slowing" as you put pressure on the work ,,, or is it me ,,,
I understand that the compound should have been set to 27.5 deg. So was the error only in what you said, or was it actually set to 22.5? If you set the compound wrong, at what point did you catch the error?
Hello If I cut thread M20 x 2 x 2 or M20 x 2 x 3. I don't know DEPTH CUT = ? (mm) How to calculate depth in multi threaded screw metric? Can you help me?
You engage the split nut and you don't disengage it until you finish cutting the entire thread, otherwise you lose tracking. that's the golden rule of cutting threads on the lathe. This ensures a rigid relationship in all relative movements between the workpiece and the tool becayse they're connected by gears in the headstock. Even when you reverse the late you can go back to your original thread starting point due to the fixed relationship of the gear train, leadscrew and split nut. You can hear him say drivenut somewhere.
why do you say 22.5 deg and the writing says 27.5 deg. and why use a roughing tool and then have to re grind it for finishing. isn't it easier to just use a insert.
JD Wisdom i work over seas, but yes i first had a bad time with his accent, just keep trying and it will grow on you, oh and every fifth word is a british curse word. he likes to work in imperial not metric so that make it best for us also. did you see his crazy jet powered go-cart?
Nikel87 I bet my two bucks on that he's of Norse ancestry. They came to North America a thousand years ago, stayed a couple of years, discovered there were people already living there for ten thousand years and then ran home with their tails between their legs screaming "I can't understand what they're saying". Maybe John could start speaking real slow and only use one syllable words and make JD happy.
Outstanding craftsmanship both on the lathe and on the camera! Thanks for sharing John!

Great camera work John, keep up the good work brother, greetings from Co wexford Ireland 👍🏻👌🏻👏🏻🍀🇮🇪
Great video. I'm going to show it to my students. They will see more than cutting the thread, you actually go over several lathe components and demonstrate how they work. This is awesome!
+Always Learnin' Thanks for the kind words Feel free to use the video RegardsJohn
Thank's John. Sincerely, for me, as an amateur this was a well demonstrated valuable lesson.

John good stuff, ideal way of showing the job from start to finish for the novice or home shop. This is a good reference video, well done Bruce.
i've been imagining this, though it is one of the easiest method, and this man in video is really intelligent as he showed it up ! thank you sooooooooooooooooo much for uploading this video.
I've just come back to this video for a refresher, John...excellent stuff.
(Funny seeing the Boxford again...and the magnet-mounted dial!)
Wonderful to See a true craftsman at work.
Thanks for the Vids John.
Thank you very much, I am still a novice so I find your videos very interesting and educational
Thanks for taking the time topost this video. I have learnt something else to try on my lathe. Cheers Fella.
excellent job john nicely turned thread nice to watch a craftsman at work thanks for uploading the video
John,
Looks like the finished item will work just fine! Thanks for another great job and sharing it with us!
Have a good one!
Dave
If you are not handy with tools, John would be a good friend to have!
Great video - excellent photography and outstanding demo and explanation.
It was nice to see the process for making the too. Thanks for showing this.

Great video I am South African and have no problem with your accent
Great video John. I love threading on the lathe. Too bad I don't need to do it more. Thanks for sharing.
Hello sir,i just bought an very old lathe and i want to make a dummy spindle for making some backplates for some chucks i have, i just find your video realy helpfull!
Thank you!
Nice work there John, thanks for sharing!
Nicely done John! Thanks for sharing.
Very interesting seeing this done slowly and close up.
Nice job on the treading, I liked the close up shot. thanks, Randy
Thanks John good videos I got my self a Harrison L6 its another lathe saved from being scraped
Great video john its great to see lathe projects again :)
Lovely fit. Your Boxford certainly is a versatile lathe.
Excellent demonstration with a purpose!
Well done John excellent sharp video.
Great video, great machine work
Tim NZ
Wow! Very nice work indeed John!
Another neat and informative video. Thanks John
That was an outstanding job John, again!! And I'm still lerning, thanks for that buddy ;-))
this video so good i had to watch it again. thanks for some great info and great work!
Looking good as always John...and I didnt get the urge to have a snack this time...LOL
Great camera work as well, you put a lot of time into it!
Colin ;-)
Gotta love inverters!
Wouldn't be without one. .. . .
Great video; great to see the work done.
This is highly educative, thank you
Always enjoy your videos John but you've really upped your game on the filming here. Very professional looking. Andy

Very trick. Thanks for sharing. Especially the details.
doubleboost Great work as usual. Do you plan on making that into an adapter for your lathe there? Bore the inside and thread it for your spindle nose? Very nice work, you sure can't complain about the finished product after you put that indicator on there.
Beautiful job. I wish my lathe would turn that slow. Thanks
Hi Amazing Videos I've watched 1 & 2 and they are Fantastic. Keep up the great work. Subed. Kind Regards Nick.
You are a clever man.
it's really wonderful..congratulations...
you need a sensor at the end of the thread and an electromagnet for clutch disengagement. To fit the lock solenoid actuator from the car alarm. The sensor may be a simple switch
Is that a Whitworth thread? ANSI threads are 60 degrees.
Great video. Reminds me of watching dad cut threads on the old lathe he had in the garage.
Great job!
Great video!
Smashing video, Very informative ;-)
Congratulations!
Brilliant, well explained and understood, iv'e just got a Boxford CSB, wonder if i can do thread without the gear box ?
Nice one John! I had to LOL @ the "wooden head" bit. But that brings up an odd question... If Pinocchio told the same lie repeatedly, would his nose grow only once, or grow each time?? If each, the same length every time? Or exponential growth per occurrence? Damn, I think too much! :))
hi ya double ,, great vids ,,, my boxford bud is also run on an inverter ,, do you have problems with the machine "slowing" as you put pressure on the work ,,, or is it me ,,,
Might have missed it, but are those Whitworth threads? Why the 55* instead of 60*? Excellent job, you make that look very easy.
He said Whitworth in the beginning of the video.
I understand that the compound should have been set to 27.5 deg. So was the error only in what you said, or was it actually set to 22.5? If you set the compound wrong, at what point did you catch the error?
The compound was at the correct angle (I have it marked)
The protractor was just for demonstration
No idea why I said 22.5
great video thanks. what in verter do you use please?
are you going to thread the other end ? or no?
Great stuff, no fancy tricks just good machining, thanks fella (should that be canny man?)
+Ian Skeldon Bonney Lad will be fine
Great video, thanks. Where's that accent from?Just curious.
What is the name of this stone? ....1:47
Isn't it 27.5 degrees lol.
But why my threads are going on one side when am using that method
i'm dying - engage our nuts... my nuts are fully engaged, I tell ya. Love the videos.
Hello
If I cut thread M20 x 2 x 2 or M20 x 2 x 3. I don't know DEPTH CUT = ? (mm)
How to calculate depth in multi threaded screw metric?
Can you help me?
How are you bringing the lathe to the same position each time.
You engage the split nut and you don't disengage it until you finish cutting the entire thread, otherwise you lose tracking. that's the golden rule of cutting threads on the lathe. This ensures a rigid relationship in all relative movements between the workpiece and the tool becayse they're connected by gears in the headstock. Even when you reverse the late you can go back to your original thread starting point due to the fixed relationship of the gear train, leadscrew and split nut. You can hear him say drivenut somewhere.
why do you say 22.5 deg and the writing says 27.5 deg. and why use a roughing tool and then have to re grind it for finishing. isn't it easier to just use a insert.
hahah the machine its so cute..heheh..
Made in ?
Well done. Very informative. Nice video. However I did struggle at times with your accent. i kept thinking "what did he say there ?"
Why don't you just use the half nut ???
I think he's geordie from Newcastle. Up North East. I'm from Manchester Northwest.
He's a Geordie. They don't do foreign,.
27.5 wooden head
11:17 dog bark ?
Have you given any thought of learning to speak "American" so us poor bastards in the colonies could understand you? Thanks, JD
JD Wisdom you dont like listening and learning from john GO ELSEWHERE!!!!!
Jamie Buckley He's the import. I live here and my ancestors lived here before any of you imports showed up. So you and he can go elsewhere.
JD Wisdom i work over seas, but yes i first had a bad time with his accent, just keep trying and it will grow on you, oh and every fifth word is a british curse word. he likes to work in imperial not metric so that make it best for us also. did you see his crazy jet powered go-cart?
JD Wisdom I'm pretty sure your ancestors where "Imports" to.
Maybe you're Swedish, or Scottish.
I bet you're not a Native.
Nikel87 I bet my two bucks on that he's of Norse ancestry. They came to North America a thousand years ago, stayed a couple of years, discovered there were people already living there for ten thousand years and then ran home with their tails between their legs screaming "I can't understand what they're saying".
